Abstract
A mathematical model of sintering process has been developed, in which considerations have been given to the combustion of coke, drying process of solid, the composition of lime stone and the meltingand solidifying process of iron ore. Variations of physical properties of gas and solid particles with the change of temperature have been taken into consideration.
The partial differential equations gave numerical values, at various depths in the bed and at various times, of the temperature of solid particles and gas, the radius of coke and lime stone particles, the concentration of O2 and CO2 gas, the combustion velocity, the decomposition rate of lime stone, the moisture content of solid and the melting rate of iron ore. Typical results are illustrated.
